I would say E.
(1) The fact that S's range is greater than T's range does not mean that S's SD is greater. Furthermore, you don't know the number of integers in either range. For example, set S could consist of (2, 4, 6, 8, 10) and set T could consist of (3, 7, 10). In this case, the range of S > T but the SD of T is > S.
(1) and (2) together are also insufficient.
I think I can. I think I can. I think I can.
